电子节流阀是一种直流伺服驱动器，它定位节流阀板，从而提供发动机扭矩的线控控制。提出了一种基于近似模型的电子节流阀鲁棒非线性控制（AMRNC）策略。AMRNC包括两个主要部分：近似模型控制器和不确定性补偿。近似模型控制器作为前馈控制器，利用泰勒展开技术对对象的输入输出模型进行线性化，并利用模糊系统建模来实现。此外，在反馈结构中采用鲁棒滤波器作为不确定性补偿。利用Lyapunov稳定性定理建立了系统的鲁棒稳定性。仿真和实验验证了AMRNC策略的有效性。
An electronic throttle is a dc servo drive which positions the throttle plate, thus providing drive-by-wire control of engine torque. In this paper, an approximate model-based robust nonlinear control (AMRNC) strategy is proposed for electronic throttle valve. The AMRNC includes two main parts: approximate model controller and uncertainty compensation. The approximate model controller, utilized as a feedforward controller, is developed from a linearization of the input-output model of the plant using Taylor expansion technique, and it is implemented using fuzzy system modeling. Moreover, a robustness filter in the feedback structure is employed as uncertainty compensation. The robust stability is established by Lyapunov stability theorem. A simulation and an experiment are provided to verify the effectiveness of the AMRNC strategy.
